NASA had enough government money to continue its programme of lunar exploration. It calculated that there were sufficient funds for nine more missions after Apollo 11. Apollo 12， which went to the moon in November 1969， and collected moon rocks， was a great success.

But the '60s were coming to an end， and some people's attitudes to space exploration were changing. An American flag now flew on the moon， so some people thought that the USA had already won the spacerace. Others associated the moon programme with the politicians who had led the USA into an unpopular war in Vietnam， in Southeast Asia.

Even within NASA itself， some people felt that it was time to abandon moon exploration. Humans had been to the moon twice what was the point of risking lives by sending further missions when there were other areas of space to explore？ But in the face of such opposition on 11 April 1970， Apollo 13 took off as planned.

At first everything went well. The launch was smooth， and for the first two days of the three-day journey to the moon the spacecraft worked perfectly. Then there was a loud bang， as one of the astronauts turned on a fan in the oxygen tanks.

A radio message was sent from the spacecraft： “Okay， Houston; We've had a problem.”

They still had a problem， a big one. Although they did not know it yet， astronauts James Lovell， John Swigert and Fred Haise were facing a fight for their lives. Oxygen tank Number 2 had exploded when its fan was turned on. This had caused Apollo 13's other oxygen tank to burst its pipes and spill oxygen out of the side of the spacecraft. Soon the command module was virtually useless， and the astronauts were forced to through into the lunar module， named Aquarius should have been used for the moon landing. It was not designed to support three astronauts， and they had to use minimal power.

Low on oxygen and fuel， the astronauts nursed their spacecraft the rest of the way to the moon， around the lunar orbit and back towards earth. Once again， the drama of the space race caught the attention of millions of people. During the whole journey the world held its breath， waiting to see if the astronauts could survive against all the odds aboard the ruined capsule. They did make it back safely， splashing down in the Pacific Ocean on 17 April 1970. NASA official Robert Gilruth said that Apollo 13 had been a frightening reminder that “Flying to the moon is not just a bus ride.”

President Nixon visited NASA not long afterwards， awarding medals to the flight controllers who had helped save the Apollo 13 astronauts. But the White House had already let it be known that space was no longer a national priority.
